GEORGE \V. EVANS, OF BROOKLYN, NEI/V YORK.

PAPER-CUTTING MACHINE.

SPECIFICATION forming part 0f Letters Patent N0. 475,761, dated May 31,1892.

Application filed January 6, 1891. Serial No. 376,897. (No model.)

To all whom it may concern:

Be it known that I, GEORG-E WV. EVANS, a citizen of the United States,residing in the city of Brooklyn, county of Kings, and State of NewYork, have invented a new and useful Improvement in Paper-CuttingMachines, of which the following is a specification.

My invention relates to improvements in machines which are applicable tothe manufacture of various kinds of paper and products thereof-such asrooting-paper, liningpaper, wall-paper, &e.-and such a measuring andcutting machine usually forms a part of the plant required for themanufacture of such paper fabrics, arranged so as to move in unison withthe other parts of the necessary machinery.

The object of my improvement is to provide for measuring and cuttingsuch paper fabrics into the desired length by mechanism having positiveand unfailin g action, combined with strength and durability, themethods heretofore in use failing in these requirements. I attain thisobject by the mechanism illustrated in the accompanying drawings, inwhich- Figure lis a front elevation. Fig. 2 is a side elevation. Fig. 3is a central section along the line 3 3, Fig. l. Fig. 4 is a plan view.Fig. 5 is a rear View of part of Figs. l, 2, and 3; and Fig. 6 is ahorizontal section along the line G 6.

Similar letters referto similar parts throughout the several views.

A is a frame, iiXedly attached to any stationary support or table, (notshown,) upon which part of the other plant for the manufacture of thepaper fabric may be mounted. Motion is given to one of the gear-wheels BB from any suitable adjacent mechanism in motion, such connection to apower-shaft not being shown. The driving-wheels B` B gear with wheels CC, mounted upon shaft C', which carries the roller C2. The shaft D'carries the upper roller D2, usual mechanism being provided (not shown)for adjusting the pressure of top roller D2 upon the paper E, which isbeing passed in the direction of the arrow between the two rollers, theroller D2 being driven by roller C2 by contact and pressure only throughthe intervening paper E. The inner frame F has endwise-sliding motion upand down within the outer rocking frame G, which latter is hinged to thestationary base-plate I-I at 7L h.

Arocking inotionis given to the frame G by the connecting-rods I I, eachhinged at one end upon a wrist-pin b upon the wheels B B or O C and atthe other end upon pin g upon the frame G. The rod K, which isadjustable in length by the sleeve-nut Il, is pivoted at` its lower endat Z to the base-plate H, and at its upper end Z2 to the block M,arranged to slide endwise within parallel ways upon frame F, whichchamber the vertical edges of block M. Consequently when the frame G isturned upon its pivots 7L 7L away from the rollers O2 D2, whereby theupper end of rod K is brought farther from the base H, the block M israised, and it is lowered by the reverse motion. This oscillating motionof block M is made to turn the ratchet-wheel N, as follows: The bar m,Fig. l, which is riveted to block M, forms a pivot at m for thepropelling-pawl m2, which is pressed toward wheel N by spring n. Thecheck O serves to prevent the pawl from skipping a tooth. a is theratchet which, with its spring n2, prevents the wheel N from turningbackward. The spindle n3, upon which the ratchet-wheel N is iXedlymounted, extends through the frame F and fixedly carries upon its otherend the flanged disk P, Figs. 2, 3, 5, and G, which has a side notch Pin its periphery, Figs. 5 and 6, into which the bar Q drops whenregistering therewith, as follows: One end of the bar Qis hinged at q toframe F and the other end is guided by slotted piece q', which isattached to frame F, so as to allow horizontal motion, but to checkvertical motion. The bar Q is continuously impelled toward beam R byspring r, but is prevented from yielding to the spring by the projectingflange of disk P until the notch P in the latter registers with the barQ. Thereupon the bar Q moves toward frame F and its lug q2 intervenesbetween lug m3 upon block M and lug f upon frame F. Consequently whenblock M is caused to rise through rod K, as described, the frame F ismade to rise with it, and thereby the knife S, which is firmly attachedto frame F, is caused to move toward the corresponding knife T, which isxedly attached to frame G, and to sever the intervening' paper E. Bymeans of the said sleeve-nut L upon rod K the length of the latter, andtherebyY the stroke of the under knife S, is made adjustable. Upon thenext motion of frames G and F toward beam R the detent r2, which isiixedly attached to beam R, pushes the bar Q out of IOO the notch p andretains it so until the ratchetwheel N has been revolved su flicientlyto unregister the notch p from bar Q. Upon the roller U is the belt V,which carries the paper E toward other operating plant arranged to givethe paper the required finish and to roll it into marketable packages.

W` WV are bars which support and guide the paper between the rolls Cl2D2 and the belt V. These bars are hinged at one end upon a transverserod X, Fig. 4, which passes thro ugh loops in the ends of bars W, rod Xbeing attached at the ends to the frame F. To facilitate the raising offrame F, springs Y are interposed between it and the frame G,approximately supporting the weight of the frame F and its attachments.There may bc several notches P in disk P, either equidistant, so as tocut the paper fabric of equal length, or otherwise, so as to cut thefabric of various lengths.

\Vhat I claim as my invention in a paper measuring and cutting machine,and desire to secure by Letters Patent, is

l. A pair of rotating rollers to feed the fabric between them,incombination with one of the cutting-knives and an outer frame to whichit is attached, said frame being hinged at the bottom to a fixed base,rods pivoted to said frame at its upper end, a rotating wheel to whichsaid rods are pivoted at their opposite ends, the second knife, an innerframe to which it is attached, said frame sliding endwise within groovesin the outer frame, a radius-rod pivoted at its lower end to the fixedbase, a block sliding endwise within said inner frame and having theradius-rod pivoted thereto at its opposite end, and means for connectingthe sliding block to the inner frame at intervals to give a cuttingmotion to said second knife.

2. The knife T, the outer frame G, to which it is attached, Jthe fixedbase II, to which said frame is hinged at the bottom, connectingrods I,pivoted to said frame at its upper end, and a rotating wheel B, to whichsaid rods are pivoted at their opposite ends, in combination with theknife S, the inner frame F, tovwhich it is attached, the radius-rod K,the base Il, to which it is attached at its lower end, the block M, towhich said rod K is attached at its upper end, block M being adapted toslide endwise within frame F, and bar Q, arranged to intervene atintervals between block M and frame F, whereby cuttin g motion isimparted to knife S at the desired intervals, substantially asdescribed.
